Description

High humidity material pulverizer

[technical field]

The utility model relates to a pulverizer, in particular to a high-humidity material pulverizer.

[Background technique]

In recent years, with the continuous advancement of the green circular agricultural industry, the structure of fertilization in the vast rural areas is constantly being adjusted. Organic-inorganic compound fertilizers that improve soil, improve the comprehensive utilization rate of fertilizers, and improve the quality of crops, especially cash crops, are becoming more and more popular. The majority of farmers accept and love it, and as the source of organic raw materials for the production of organic-inorganic compound fertilizers: domestic garbage, poultry manure, sludge from treatment plants, etc. are all subject to crushing procedures when they are produced into organic raw materials, because these Raw materials must be added with straw powder, rice bran, mushroom soil and other substances when making fertilizer by biological fermentation. The addition of these substances brings in a lot of wood fibers, and some raw materials have their own wood fibers, such as cow dung, pig manure, etc. These When the water content of the raw materials is low (it is easy to crush when the water content is below 8%), it can be processed by ordinary blade mills or other pulverizers, but the initial water content of these raw materials is very high, reaching more than 80%. The water content after oxygen biological fermentation is still about 35%, and it must be dried before being crushed, and these materials need to add some water in the next granulation process, so it is very difficult to crush after drying, and it also causes a lot of energy waste . Ordinary blade pulverizers must be equipped with a screen under the knife roller to control the direct throwing of uncrushed materials, because high-humidity materials will quickly block their inner chambers or screens, so ordinary blade pulverizers Materials with a high water content cannot be processed at all. Since this high-humidity material cannot be pulverized and cannot be co-granulated with inorganic raw materials to produce granular organic-inorganic fertilizers, the high-humidity material pulverizer has always been the bottleneck in the large-scale production of organic-inorganic compound fertilizers.

[Content of the invention]

The technical problem to be solved by the utility model is to provide a pulverizer suitable for processing high-humidity materials.

In order to solve the above technical problems, the technical solution adopted by the utility model is that a high-humidity material pulverizer includes a feed port, a discharge port and a shell, the shell includes a wallboard, and the feed port is opened on the top of the shell , the discharge port is funnel-shaped, and also includes the main cutter roller, auxiliary cutter roller and hanging baffle; the main cutter roller is a circular cutter roller, and the auxiliary cutter rollers are two circular cutter rollers with the same diameter and smaller than the diameter of the main cutter roller; the main cutter roller The central shafts of the auxiliary knife roller and the auxiliary knife roller are respectively installed on the wall panels on both sides of the shell, and the main knife roller and the auxiliary knife roller are installed in the shape of a finished product in the inner cavity of the shell; ;The auxiliary knife roller is installed directly below the main knife roller, and the edges of the two auxiliary knife rollers are adjacent to each other with a gap left. There are hanging baffles installed at the front and rear of the rotating direction of the roller, and the discharge port is located directly below the two auxiliary knife rollers.

The upper end of the suspension baffle is fixed on the top of the housing, and the lower end is freely hanging.

The above-mentioned hanging baffle is a flexible rubber plate.

The beneficial effect of the utility model is that the core part is composed of three knife rollers, one large and two small, the function of the main knife roller is to crush materials, and the two auxiliary knife rollers below not only play the role of crushing, but also play a role in controlling the flow of materials. The completely pulverized material is pushed back to the main cutter roller to continue crushing. At the same time, movable baffles are suspended in the inner cavity of the pulverizer along the rotation direction of the cutter roller. The material on the board falls off automatically, achieving the effect of self-cleaning and non-stick material. With compact structure and high crushing efficiency, it is suitable for crushing of materials that are difficult to crush, such as high-humidity materials.

[Description of drawings]

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Fig. 1 is a schematic structural view of an embodiment of the high-humidity material pulverizer of the present invention.

In the figure, 1-inlet, 2-housing, 3-outlet, 4-main knife roller, 5-auxiliary knife roller, 6-hanging rubber plate.

[Detailed ways]

FIG. 1 is a high-humidity material pulverizer, which includes a feed port 1 , a discharge port 3 and a housing 2 . The housing 2 includes a wallboard. It also includes a main knife roll 4, an auxiliary knife roll 5 and a suspension baffle 6. The main knife roll 4 is a circular knife roll, and the auxiliary knife roll 5 is two circular knife rolls with the same diameter and smaller than the diameter of the main knife roll. The central axis of main knife roll 4 and auxiliary knife roll 5 is contained on the wallboard of housing 2 both sides, and main knife roll 4 and auxiliary knife roll 5 are installed in the shape of a finished product in the housing. The main knife roller 4 is installed on the upper part of the inner cavity of the casing 2 and is located below the side of the feed port 1 . The auxiliary knife roller 5 is installed directly below the main knife roller 4, and the edges of the two auxiliary knife rollers 5 are installed adjacent to each other, and a certain gap is left between the adjacent places. Turning upward at the same time, its function is to continue crushing materials, and second, larger materials that have not been completely crushed cannot pass through the gap between the two auxiliary knife rollers, and are pushed back to the crushing work area. Suspension rubber plates 6 are installed at the front and rear along the rotation direction of the main knife roller 4 and auxiliary knife roller 5, the upper end of the suspension rubber plate 6 is fixed on the top of the shell with bolts, and the lower end is freely hanging, which is used to prevent crushing Materials fly out of the crushing work area. The discharge port 3 is funnel-shaped and is located directly below the two auxiliary knife rollers 5 .

working principle:

It can be seen from Figure 1 that after the material enters the inner cavity of the shell from the feed port 1, it is first crushed by the main knife roller 4, and after running downwards, due to the reverse rotation of the two auxiliary knife rollers 5, it is cut off from directly rushing to the discharge. The airflow at port 3 is crushed again by the auxiliary knife roller 5 at the same time, and part of the material is pushed back to the machine cavity by the auxiliary knife roller 5 to be crushed again, so as to achieve the effect of multiple crushing without blocking the material, ensuring the normal operation of the equipment .
